22 Marker Commands
:MARKer:X2Y2source
Command :MARKer:X2Y2source {CHANnel<N> | FUNCtion<N> | WMEMory<N> | CLOCk
| MTRend | MSPectrum | EQUalized}
The :MARKer:X2Y2source command sets the source for the Bx and By
markers. The channel you specify must be enabled for markers to be
displayed. If the channel, function, or waveform memory that you specify
is not on, an error message is issued and the query will return channel 1.
MTRend and MSPectrum sources are only available if the oscilloscope has
the EZJIT option installed and the feature is enabled.
The CLOCk source is only available if the oscilloscope has the High Speed
Serial option installed and the feature is enabled.
The EQUalized source is only available if the oscilloscope has the High
Speed Serial option and the Serial Data Equalization option installed and
the features are enabled. This command uses the Feed- Forward Equalized
(FFE) signal as the source.
<N> CHANnel<N> is an integer, 1 - 4.
FUNCtion<N> and WMEMory<N> are:
Integers, 1 - 4, representing the selected function or waveform memory.
Example This example selects channel 1 as the source for markers Bx and By.
myScope.WriteString ":MARKER:X2Y2SOURCE CHANNEL1"
Query :MARKer:X2Y2source?
The :MARKer:X2Y2source? query returns the current source for markers
Bx and By.
Returned Format
[:MARKer:X2Y2source] {CHANnel<N> | FUNCtion<N> | WMEMory<N> | CLOCk
| MTRend | MSPectrum | EQUalized}<NL>
Example This example returns the current source selection for the Bx and By
markers to the string variable, strSelection, then prints the contents of the
variable to the computer's screen.
Dim strSelection As String ' Dimension variable.
myScope.WriteString ":MARKER:X2Y2SOURCE?"
strSelection = myScope.ReadString
Debug.Print strSelection
